Objective: The goal of this study was to compare the clinical outcomes of posterior surgery with combined laminectomy and thoracoscopic surgery for treating dumbbell-type thoracic cord tumors.
Patients And Methods: We retrospectively analyzed 32 cases of dumbbell-type thoracic cord tumors treated by two surgical procedures in our center from February 2003 to July 2013. CASES WERE DIVIDED INTO TWO GROUPS DEPENDING ON THE TYPE OF SURGERY: Group A cases (n = 12) underwent posterior surgery followed by laminectomy, costotransversectomy and instrumentation; Group B cases (n = 20) underwent posterior laminectomy and anterior video-assisted thoracoscopic surgery in a single-stage procedure. Operation time, blood loss, hospitalization, recovery of neurological function, and complications were compared between the two groups.
Results: Complete surgical excision was achieved in both groups. All patients were followed up for an average of 7.4 ± 2.8 years (range, 3-13). At the final follow-up visit, there was no tumor recurrence and no differences in neurological results between the two groups (P > 0.05). However, the average operative duration, blood loss, hospitalization, and rate of complications were significantly lower in Group A compared to Group B (P < 0.05).
Conclusion: Both posterior surgery and the posterior surgery combined with anterior thoracoscopic surgery were effective for removing dumbbell-type thoracic cord tumors. However, posterior surgery alone was associated with reduced operative duration and rate of complications compared to the combined surgical approach.

Spinal dysraphism is the incomplete fusion of the neural arch, which can be seen as an occult or open neural tube defect. Meningoceles are a form of open neural tube defect characterized by cystic dilatation of the meninges containing cerebrospinal fluid without the involvement of neural tissue. Neurosurgical intervention is necessary in the newborn period since survival in advancing ages is often impossible.

Purpose: To clarify the influence of biomechanics on post-operative clinical outcomes in bicruciate-retaining total knee arthroplasty (BCR-TKA).
Methods: Severe medial osteoarthritis who underwent BCR-TKA were examined. Each patient was asked to perform a squat (weight-bearing [WB]) and active assisted knee flexion (non-WB [NWB]) under single fluoroscopy surveillance.
Purpose: Anterior tibial closing wedge osteotomy (ATCWO) has been shown to significantly reduce failure rates of revision anterior cruciate ligament (ACL) reconstructions in patients with a posterior tibial slope (PTS) ≥12°. Recent findings suggest a slight but significant reduction of the medial proximal tibial angle (MPTA) resulting in a varus knee where the sagittal osteotomy plane is based on a total of two guide wires defining the osteotomy wedge without respecting the frontal plane. We hypothesize that the placement of a total of four guide wires intraoperatively can reduce the influence on the MPTA.

Background: Gravid females with pelvic fractures are rarely encountered by the orthopaedic trauma surgeon. The initial injury can be detrimental to the pregnant patient, but an unnecessary "second hit" from surgery could also contribute to the outcome of the fetus. Understanding the surgical risks for this unique patient population requires knowledge about the negative effects of anesthesia, surgical exposures, and radiation.

The posterior mandible is the primary area for occlusal function. However, long-term tooth loss in the posterior mandible often leads to rapid absorption of both buccal and lingual trabecular bone plates and subsequent atrophy of the alveolar ridge. This ultimately results in horizontal bone deficiencies that complicate achieving an optimal three-dimensional placement for dental implants.
